DAF Variomatic

Variomatic menjac je prvi bezstepeni automatski menjac predstavljen jos 1958 godine na modelu DAF 600. Sistem je razvijen od strane Hub van Doorne-a, osnivaca kompanije DAF ( Doorne's Automobielfabriek - DAF ). Naime, van Doorne je bio fasciniran automatskim menjacima i smatrao je da su oni buducnost ali mu je smetalo sto su suvise komplikovani, teski i sto previse opterecuju motor. Zbog toga je radio na resenju lake, jednostavne i optimalne automatske transmisije za automobile.

Slika

Ceo sistem je veoma jednostavan i prakticno se sastoji dva "rolera" ( jedna povezan na motor a drugi na poluosovine ) i kaisa sa velikim V profimom. Najbitniji detalj su dve simetricne kupe, koje cine jedan "roler" i koje se razdvajaju ( i spajaju ) cineci da kais upada izmedju njih. Ovi klipovi to najbolje pokazuju:






Upadanjem ( i podizanjem ) kaisa se menja prenosni odnos, od najveceg za start do najmanjeg ( max brzina ). Sinhronizovanjem svih "rolera" ( dva po osovini ) omogucen je lep rad sistema. Specificnosti Variomatika su da ( zbog ne postojanja klasicnog rikverca ) auto opremljen ovim menjacem moze da ide u nazad jednako brzo koliko i unapred!

Prednosti ovog menjaca su bile znatne, pored komfora u voznji, male tezine, svi DAFovi su dobro lezali na putu, teoretski, ovakav prenos omogucuje da se uvek optimalan torque prenese na tockove a model DAF 55 je imao i dosta uspeha na rally takmicenjima. Mane su vise bile vezane za tehnologiju materijala tog doba i poznato je da su kaisevi cesto pucali a da su "roleri" znali da otkazuju ako je automobil cesto vozen opterecen. Ipak, iako su DAF i Volvo modeli sa ovim menjacem odavno prestali da se prave, Variomatic je veoma rasprostranjen sistem u modernom automobilizmu. Vecina svetskih prozvodjaca ga koristi ( navodno, oko 40 aktuelnih modela ga ima u nekom obliku ), moderna CVT transmisija je samo usavrsen Variomatic a neizbezan je kod skutera.

Ovo me je oduvek fasciniralo , odusevio sam se kad sam to video u jednom starom casopisu.

vozio sam se u jednom. ide ko trolejbus. cudno je skroz da nema bas nikakve promene stepena prenosa. i kod najboljeg automatika osetis bar po zvuku da je promenio brzinu. ovo cudo ne. mali je motor pa nije neko epohalno ubrzanje ali ide.

Nisam 100% siguran,ali mislim da je Volvo u ovom modelu koristio DAF-of Variomatik

Jeste, sa time sto su DAF 66 i Volvo 66 prakticno identicni automobili samo sa drugom znackom i par sitnijih modifikacija. Volvo je kupio DAF 1974 godine.

masovnom se variomatic koristi na skuterima ali uvijek ima ali jest ono bez stepeni prenos ali često se mora remen mjenjati i često se kvari :roll:

Ne bih se slozio sa tobom po pitanju pouzdanosti i kvarenja. Kais se jako retko menja,jedina potrosna stvar osim kaisa su rolnice koje menjas kad i kais i nista vise. Pod ovim ne mislim na kineske de-modele sa kojima nemam bas prijatno iskustvo...

U industriji se puno koristi ovo rešenje.Broj obrtaja el.motora je standardizovan,a nekad su potrebni obrtaji veći ili manji od standardnih ili mogućnost promene broja obrtaja.Retko,ali baš retko,dolazi do pucanja kaiša.15-ak godina radim na poslovima elektroodržavanja i samo jednom sam imao pucanje kaiša na varijatoru.

Ovaj tip menjaca se ubacuje i u male automobile od 50 ccm ( LIGIER i sl.) koji se ovde u Italiji voze bez dozvole,potrebno je imati nesto poput naseg PSP-a,ali iskreno nisam bas nesto posebno odusevljen sa njima jer prilikom naglog pustanja gasa prave prave neku buku kao da se raspadaju a i prilikom kretanja primetio sam da dosta trzaju.Neosporavam da je taj DAF-ov dobar,verovatno ulogu igraju i godina proizvodnje i kvalitet izrade,ali znam da cu ih u buducnosti izbegavati.

What's the full story about this bike? Exhibited in the DAF museum in Eindhoven, its made of various Honda parts and with a flat-two DAF 46 engine. And the DAF Variomatic transmission of course.

Lepo objašnjenje, samo jedna ispravka: menjač nije bezstepeni, već ima beskonačno mnogo prenosnih odnosa.

Ovi menjaci su danas jako rasprostranjeni. Kod Audi-a Multitronic, kod Honde i Mercedesa (A Klasa)....
